The principle and the methods for correcting the nonlinear errors of the sensor system with a neural network are introduced . Nonlinear errors correction of sensors based on BP neural network, which include its model, algorithm and realized techniques are presented.The results of computer simulations illustrate that not only the inverse modeling based on BP neural network can compensate the effect of the nonlinearity, but also the construction of the neural network is simple and the precision is good..
